STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 462,798, dated November10, 1891.

Application filed October 8, 1890. Serial No. 367,396. (No model-I Toall whom it may concern.-

Be it known that we, LEVI HUSSEY and EDWARD MCCANN, both of the city,county, and State of New York, citizens of the United States, haveinvented certain new and useful Improvements in Steam-Traps, of whichthe following is a specification.

This invention has reference to an im proved steam-trap, in which thewater of condensation from steam'pipes and other steamvessels is readilycollected andintermittently discharged; and the invention consists of asteam-trap which comprises an exterior casing or pot having asupply-pipe for the water of condensation, and a double dischargevalve,the stern of which is engaged by the downwardly-extending arm of afulcrumed elbow-lever, to the upper arm of which a fulcrumed fioat isattached. The double valve is guided in a bracket-shaped valve-casingthat communicates with the discharge-pipe of the pot and that isprovided with two vertical ports, which are opened or closed by thelateral motion of the double valve as produced by the float, accordingto the rise and fall of the water in the trap.

In the accompanying drawings, Figure 1 represents a side elevation ofour improved steam-trap. Fig. 2 is a vertical longitudinal section ofthe same; and Figs. 3 and 4. are re spectively a horizontal section onthe line 3 3, Fig. 1, and a vertical transverse section on the line 4:4, Fig. 1. v

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the exterior casing or pot ofour improved steamtrap, and A the cover of the pot. At one end of thepot A is arranged the inlet-pipe a, to which a sediment-chamberB ofanyimproved construction is applied, in which any impurities carriedalong by the water of condensation are collected, so that they do notpass to the interior of the pot. The pot A is provided at the insidewith re-enforcing ribs, which serve as guides for a float C in the pot,so as to prevent thelateral mot-ion of the same. At the lower part ofthe pot A is arranged the outlet pipe a, which is attached by a couplinga to the threaded outer end (Z ot'a bracket-sh aped val ve-casin g D,that is screwed into the wall of the pot and provided with two verticalports (Z and valve-seats (Z. In line with the center of the ports (Z andvalveseats are arranged guide-holes (Z respectively in the valve-casingD and in the closing-plug D at the inner end of the same, said holes dserving to guide the stem of the double valve D The beveled valve-disksof the valve D fit accurately on the valve-seats (1, so as to close theports (Z d. The stem of the valve D is provided between the valve-diskswith a longitudinal recess 6, that is engaged by the rounded-oft end ofthe lower arm of an elbowlever E, that is attached to a transversespindle E, which is supported in suitable bearings of the side walls ofthe casing or pot A. To the upper arm of the elbow-lever E is applied afloat F, which is balanced bya weight F, applied to an arm F at theouter end of the spindle E, as shown in Fig. 1. Both verticaldischarge-ports d of the valve-casing D are connected with thehorizontal part of the same and with the outlet-pipe, so that when thewater of condensation is gradually filling the interior of the pot A thefloat is raised and thereby both valves opened simultaneously, so thatan immediate discharge of the water of condensation through both portstakes place.

The bracket-shaped valve-casing D is provided with an octagonal boss (Znext to its threaded end, so that it can be readily taken hold of by thewrench when screwing it into the pot or for removing the same. The plugor cap D, that screws into the opposite end of the valve-casing D, canalso be readily removed by means of a wrench, so that the double valve Dcan be readily removed for repairing the same. By the arrangement of twovertical ports the valve-disks do not obstruct the free exit of thewater, so that sediments and scales may pass out freely with the waterof condensation. By arranging two valve-disks and balancing the floatthe valve is rendered very sensitive and is easily operated under highpressure. The opening or closing of the vertical ports is readilyobtained, and thereby the full area of the main discharge-pipe availablefor the outflow of the water of condensation by a very small movement ofthe valve, which is reliatical ports having valve-seats on their innerfaces and sockets in their outer faces, and a Valve-spindle adapted toslide in said sockets and provided with valves adapted to rest on saidvalve-seats, said spindle beingoonneeted with the other arm of saidelbow-lever, substantially as described.

In testimony that We claim the foregoing as our invention We have signedour names in presence of two subscribingwitnesses.
